The fruit known for being the primary source of dietary fiber is the apple. Apples are rich in both soluble and insoluble fiber, which is important for digestive health. The soluble fiber, particularly pectin, can help lower cholesterol and stabilize blood sugar levels. Eating apples can promote feelings of fullness, aiding in weight management. They are also low in calories and packed with vitamins, minerals, and antioxidants, making them a nutritious addition to any diet. Consuming apples with the skin on maximizes their fiber content and health benefits.
